  Really helpful and great service

  Posted 22 April

  Had a Trianco air source heat pump installed and couldn’t be happier with the whole experience. The team were professional from start to finish, explained everything clearly, and the install was completed to a really high standard. They handled all the paperwork for the Boiler Upgrade Scheme, secured the £7,500 grant, and I barely had to pay anything which made a huge difference. The system is running perfectly and the 10-year warranty gives great peace of mind. Would highly recommend to anyone considering a heat pump.

  Heat pump install

  Posted 26 February

  We had our air source heat pump installed by Diamond Boilers and couldn’t be happier. The team were friendly, reliable, and did a really neat job. Everything was explained clearly and the whole process felt easy from start to finish. It’s working brilliantly — we’d definitely recommend them.

  Professional and friendly

  Rob did some work for us recently and we were really impressed with how friendly and professional he was. The work carried out was to a great standard and reasonably priced. I've already recommended him to friends and would definitely use his services again if needed.

  Central Heating for air source heat pump

  Posted 24 February 2025

  I can’t fault anybody from this company and I dealt with four different people. They were hard working, polite and committed to completing the work professionally . Any questions I had they answered quickly and I had a few. Wouldn’t hesitate at all to recommend this company . Great group of people

  Installing ASHP, including fitting cylinder and changing two radiators

  Posted 24 February 2025

  Very happy with our install from Diamond. Gave us an honest and straight foward assessment of what would work best. Installation took a little longer than expected but Rob and team were great at communicating everything. Installed high quality equipment at good value. Would certainly recommend. Our house is now toasty warm and spending less than we were with our gas combi.
